Activate is a new initiative designed to make healthy living easier - and more enjoyable in the moment. At the heart of the experience is our iOS app: a vibrant, highly visual service that turns small everyday choices into immediate feedback, encouragement, and a sense of progress.

We are now looking for an iOS developer who wants to take the lead and build Activate's experience together with a small, driven team.

You will thrive with us if you like to create new things, test ideas quickly and suggest features that no one has asked for (yet) – but that users will love. You will be solely responsible for iOS in day-to-day operations, with support from product design and backend when you need it.

Location: Stockholm – hybrid (at least 3 days/week in the office)

Here's what you'll do:

• Lead Developer for Activate's iOS app – drive the project from vision to finished product.

• Build modern and intuitive interfaces with haptic engine, Lottie and Core Animation
• A/B test and measure effects and implement findings.
• Set architecture, quality level, CI/CD and release flow.
• Collaborate closely with product and design on roadmap, problem-solving and priorities.
  

What you already know:

• You are experienced and comfortable working with SwiftUI
• Build reactive flows with Combine/Swift Concurrency.
• Experience in developing and integrating with REST APIs
• Animate (Core Animation/Lottie) and optimise performance.
• Write testable code (XCTest, preferably snapshot/UITest) and use Fastlane/similar for deliveries.

Desirable (nice if you can/are curious about): HealthKit/Core Motion, Push/Remote Config (e.g. Firebase), in-app purchases/subscriptions (StoreKit), deep links, accessibility, analytics (Amplitude/GA/Mixpanel/Firebase).

And you as a person?

• Self-starter, responsible and proactive – you don't wait for a perfect backlog.
• Creator at heart: you find solutions, prototype quickly and iterate.
• Structured enough to maintain production pace and quality. Doesn't dwell too long.
• Communicates smoothly in Swedish (or Norwegian/Danish) and English.
• Thrives in small teams where everyone helps each other and celebrates small victories.

Why Activate?

• Build something that actually helps people now, not “later”.
• Small, agile environment with great ownership and few dependencies.
• A product with a clear personality: playful, visual and warm – where “fun to use” is a requirement, not a bonus.
• A modern tech stack that you get to help shape – together with colleagues who truly care.

Practical

• Scope: Full-time.
• Start: As soon as possible.
• Location: Stockholm (hybrid, at least 3 days/week in the office).
